Hot iron branding causes significant acute pain and lasting tissue damage in cattle used for individual identification, while electronic and freeze branding alternatives offer better welfare outcomes.
Cattle subjected to hot iron branding experience intense burning pain followed by weeks of wound healing during which the damaged tissue is painful and susceptible to fly strike. The availability of electronic identification and freeze branding that achieve the same permanent identification purpose with far less welfare impact makes hot iron branding difficult to justify ethically. Regulatory requirements mandating alternatives and certification scheme prohibitions on hot iron branding drive adoption of more humane identification methods.
